Abstract

The invention provides a phase-change interior wall paint composite material, which comprises emulsion paint and microcapsules, and the weight percentage of the microcapsules is 5%-30% on the basis that the total weight of the interior wall paint composite material is 100%. According to the phase-change interior wall paint composite material provided by the invention, the emulsion paint and the microcapsules are compounded for use, and the emulsion paint is used as a paint surface coating and also used as a binder for fixing the microcapsules to form an interior wall surface coating. The invention discloses a phase-change interior wall paint composite material. When the temperature of the microcapsule reaches the phase change temperature, a phase change process is generated in the capsule,and the phase change material converts external heat into self latent heat or releases the self latent heat into an external environment, so that the system is kept in a constant-temperature state, therefore, indoor temperature fluctuation can be reduced, the indoor temperature can be kept comfortable in summer and summer, the indoor temperature can be kept at a good thermal comfort degree, and energy conservation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of interior wall paint, in particular to a phase-change interior wall paint composite material. Background technique [0002] Interior wall latex paint is a kind of coating with polymer emulsion as film former, and it is a kind of water-based coating formulated with synthetic resin emulsion as base material by adding pigments, fillers and various additives. Interior wall latex paint is one of the main decorative materials for interior walls and ceilings. It has the advantages of good decorative effect, convenient construction, little environmental pollution, and low cost. It is widely used. With the enhancement of environmental awareness and the improvement of living standards, materials in the construction industry are gradually becoming intelligent and multi-functional. [0003] The climate of cold winter and hot summer brings discomfort to people's life. Various solutions have been sought to reduce clim...
